If you're here, you're likely replacing a filter in an Aprilaire, Lennox, or White-Rodgers whole-home media cabinet — this is a specialized size with no generic alternatives, and these are the direct OEM cross-references.
Compatible systems and part numbers:
- Aprilaire #401 — the standard replacement for Aprilaire media air cleaners using this housing size
- Lennox X5425 — OEM cross-reference for Lennox whole-home filtration systems
- White-Rodgers FR1400-401 — direct replacement for White-Rodgers media cabinet systems
All six SKUs are available in MERV 8 (standard dust and allergen control) or MERV 11 (finer particle capture including pet dander, mold spores, and smaller pollen), sold in 2-packs.
Not sure which MERV rating your system specifies? Check your existing filter's label or your system's installation manual, or call 1-800-277-3458.
